Abstract:The design and preparation of hybrid mixed matrix membranes based on PVC (polyvinylchloride) were studied for the separation of toluene-n-heptane mixtures by pervaporation. PVC was chosen as the starting organic matrix because it is an inexpensive polymer, possessing a very high selectivity for aromatics. This property is due to the polar macromolecular structure that can induce a specific transfer of aromatic species compared with aliphatic species. To improve the performance of the PVC glassy struc…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
